Transitional boundary layers in low-Prandtl-number convection
Jörg Schumacher, Vinodh Bandaru, Ambrish Pandey +1
The boundary layer structure of the velocity and temperature fields in turbulent Rayleigh-Benard flows in closed cylindrical cells of unit aspect ratio is revisited from a transiti…
Phenomenology of buoyancy-driven turbulence: recent results
Mahendra K. Verma, Abhishek Kumar, Ambrish Pandey
In this paper, we review the recent developments in the field of buoyancy-driven turbulence. Scaling and numerical arguments show that the stably-stratified turbulence with moderat…
Dynamics of large-scale quantities in Rayleigh-Bénard convection
Ambrish Pandey, Abhishek Kumar, Anando G. Chatterjee +1
In this paper we estimate the relative strengths of various terms of the Rayleigh-Bénard equations. Based on these estimates and scaling analysis, we derive a general formula for t…
Scaling of large-scale quantities in Rayleigh-Bénard convection
Ambrish Pandey, Mahendra K. Verma
We derive a formula for the Péclet number () by estimating the relative strengths of various terms of the momentum equation. Using direct numerical simulations in thre…
Near isotropic behaviour of turbulent thermal convection
Dinesh Nath, Ambrish Pandey, Abhishek Kumar +1
We investigate the anisotropy in turbulent convection in a 3D box using direct numerical simulation. We compute the anisotropic parameter , wh…
